Unwillingness to assist by a Business Banking Consultant

I attempted to register for for a business account online banking last night, I registered until the stage where the system says a consultant will call to conclude the registration. Then today at 09:27 I get a call from a consultant who requests me to give her my business account number. I then requested that she should call me after 10 minutes because I was not at my desk where my documents are, I do not know the account number by heart as it is a new account. She then flatly refuses to do that and the reason she gives is that she has other clients to assist so she cannot call me in 10 minutes. Even trying to get her to re-schedule the call for someone who will be willing to call me back was met with a rather rude "Goodbye Sir!". I informed her I will report this unwillingness to assist me she did not seem to care at all. Either this person needs training on customer care or is simply disinterested in her job I do not understand which is which. A rather disappointing first experience of FNB Business banking. I have been doing personal banking with FNB for many years and I have never met this kind of unwillingness to assist!!
